Abstract

With the acceleration of urbanization and industrialization, regional development is becoming increasingly disordered. Thus, how to balance economic development and ecological protection is a key question. To comprehensively evaluate land development suitability, an evaluation index system for construction land and farmland suitability was established in this study based on natural and social-economic information. After selecting an island in China as the main case study in this work, the reference method was applied in grading and value assigning for all indices. In addition, the analytic hierarchy process and expert evaluation method were used to determine the index weighting. After scenario analysis was adopted in the study to analyze the impact of the policy orientation on the suitability evaluation, we finally evaluated the landscape ecological quality of different scenarios. Results showed the landscape ecological quality of a coordinated development scenario was the highest. The results indicated that coordinated development which takes the ecological protection and urban development into account may be a better choice for land planning.

Highlights

With the acceleration of urbanization and industrialization, a large amount of farmland and woodland have been occupied by urban and construction land
Scientific and comprehensive land development evaluation has been recognized as being critical for assessing the land suitability for specific use and planning for future land use and management [4,5,6]
After construction land and farmland suitability evaluation, we proposed three different land suitability evaluation programs of the island based on different development goals, which are as follows: (1) Economic priority program

Summary

Introduction

With the acceleration of urbanization and industrialization, a large amount of farmland and woodland have been occupied by urban and construction land. Scientific and comprehensive land development evaluation has been recognized as being critical for assessing the land suitability for specific use and planning for future land use and management [4,5,6]. Land suitability evaluation is a process used to assess land suitability for a specific purpose [7], which can provide a comprehensive view for land development and planning and promote scientific and rational use of land resources [1,6,8,9,10,11,12]. Since the 1970s, Geographical Information Technology has promoted the development of land suitability evaluation [8,9,14,15,16,17,18,19]. With advances in data collection and processing technology, land suitability evaluation has been gradually applied in various fields, such as crop suitability processing technology, land suitability evaluation has been gradually applied in various fields, such Sausstcarinoapbilsituyi2t0a1b7i,l9it, y12e92valuation [20,21,22,23,24], landscape planning [25,26], waste management planning2 [o2f71–5
